To all whom it mayconcern: v 3 Be it known that GEORGE D.=Horrns, a

citizen of the United States, residing at Springfield, in the county of C'lark and State of Ohio, have invented certain new and useful Improvements in Trolley-Rephcers; and I do hereby declare the following to be a full, clear, and exact description of the in-' vention, such as will'enable others skilled in the art'to which it appertains to make anduse thesame. v

T'lllS lllVeIltlOIllfilittGs to new and usetul improvements in trolley replacers and has .co6peratingj -wheels ar held yieldinglywhich .is a i trolley-wheelimposition ont-he tr'olley w re 1 1 F'gure. Itris a rear 'Iview of v showing the improved v'attachment as 1t..

for its ohject the provision of-such a device pted o automatically replace a should tliEsanie-j become dislodged.

Another ob ect of my invention 1s the provision of ameans by which the trolley.

wheel and the'r mechanism is supported. I A still further object of the-invention is the provision ofa novel means whereby the against the trolley wheel support.

Withtheahove and other objects in view I will now proceed to-describe the invention r in 1 the following" specification and. accompanyiiig drawings, in which,

{would appeanwhen in place, one portion of ,saidettafchnient being in section toumo're clearly illustrate the interior mechanism thereof, and Fig. 2 is a detail sectionalview taken-0n line 2 -2 of Fig. 1.

Referring more part1cularly t ings'l indicates a trolley pole'of the ordi nary type, which is secured to a car, in the Y usual manner. This trolley pole'is prefer ably. provided adjacent its upper end with the apertures 2' through which the holts B,

or other securing means, are adapted to pass: l A suitable sleeve 4, having formed at'its upper end at diametrically opposite points the outwardly extending arms 5, is provided and is adapted to'be'secured to the trolley pole by means of the bolts previously de scribed. At the lower end of the sleeve 4 and formed integrally therewith are also provided the outwardly and upwardly .extending arms 6 which-join the arms 5 as clearly illustrated by the numeral 7. Ex-

tending upwardly from the endsof the arms 1 5. and; and at substantially right angles to they longitudinal plane of the arms 5 are .alsoprovided the portions 8, having the i'e-J Specification of Letters Patent.

cesses-9 formed adjacent'their upper, ex? Centrally located! with relation to the longitudinal axes 'and' adjacent the tremities,

upper ends of the portions 8' are also provided the apertures 10- through which the endsof the. axl of thetrolley wheel are adapted to exte l ll.

The axle, above cated generally by the numeral 11, is preferaxle in position.

terminate in the enlarged portiohs 1&- Genreferred to, which is india trally'locatedapertures 17 are formed in, v

the arms or" the U-shaped member "and are adapted to receive the axle 11 when the device is in use, i

The trolley wheel which-is indicated by the numeral vl8 and formed in' the usual manner, is rotatably mounted on'the axle intermediate the arms of'the I l -shaped mem her 14; as will'be clearly seen upon referring Rotatably mounted onthe'axle. and intermediate the U-shaped member 1 1 andthe portions 8 1 preferably provide thecofn eshaped wheels, indicated generally by the numeral l9. These. cone shaped wheels are.

provided with the spiral grooves 20 which extend from the outer ends of said wheels to the inner ends-thereof. The smaller di- '-a meters of the cone-shaped wheels are placed outwardly, as clearly illustrated, and provided with the inwardly extending cylindrical recesses 21,. in which the compression} 'ucoi-l jspringsrZQ are adapted to seat when the device is in place. These coil springs 22 areadapted to abut thetinner walls of the recesses and theother v ends of "said springs are adapted to abut the portions 8. Thus it will be seen that the inner ends of the cone-' shaped wheels will'he held yieldingly into engagement with the arms of the ljrsh'aped member 1d, thereby holding the inner flanges of the wheels 19 in close proxim ity to the trolley wheel 18;

It will be, clearly seen from the foregoing thatin use my improvedtrolleyreplacer, 'may be secured to the end of a trolley poleof the -,ordinary type as clearly shown 'in the drawings, and should the wheel 18 jump from its position oil the wire it will be ap-' =.-a'ent that by meansTof-the spiral grooves I 2.10 which extend around the cone-shaped as-heels 19 it will be automatically replaced.

Thus, it will be seen that should thetrolley Wheel jump from its position on the wire and either 01- the Wheels 19 engage-the wire through the action or the spiral grooves the trolley pole will. travelaoross and the wheel 18 will be replaced in its normal position on the Wire.

While in the foregoing I have shown and described the preferred embodiment of my invention I wish it to be understood that I may change the specific arrangement and coi an or parts, without in anyway depart 1i i the spirit and scope of'my ini'enti ed in the appended claim.

liiiat 1: is

a trel placer, a supporting frame adapted tachable attachment to a trolley pole, an atle carried by said frame, a substantially ti-shaped braeizet detachably carried by said frame and having substantially semi-circular shaped enlargements formed upon the terminals of its legs, a v

oone shaped Wheels mounted'upon said axle trolley Wheel carried by said axle intermediate of said'legs and having its periphery in line with the. edges of saidsubstantially semi-circular enlargements, substantially and having their basespositioned in ehgagement Wit-lithe outer surface of the legs of said bracket and the outer surface of said substantially semi-circular", enlargements,- the faces of said cone shapedv heels being or larger diameter than said trolley,v said substantially cone shaped wheels being pror vided with peripheral spiral grooves leading to their bases, and means for holding.

said bases in engagement with the outer sure face of said substantially semircircular shaped enlargements and-the legs of said brackets. I

In testimony whereof I my signature 0 in presence or" two Witnesses.
